Why did this happen?

Cause thrips and other bugs attack, during the end of flowering stage, the bugs bite on the flower ovary or baby fruits, then after the fruit grown, there will be a scar on the surface.

How to prevent this?

Solutions:

1.Use Spinetoram, before the followering period, this is the pesticides specialise on thrips. (Of course, imidacloprid or acetamiprid could be a choice, but the dosage should be increased, and these two will cause resistance to drugs)

2.Supply enough Boron and Calcium by foliar, to improve crop resistance to disease. As Andatrace elements, and Megaswell.

Andatrace elements contains of various of trace elements one solution for all crops in different stage. And megaswell products, mostly provide with Ca&Mg.
